Hi All,

I am calling that round compression ring thing that goes
over your toilet's inlet water pipe (1/2" copper?) a nipple.
If I am wrong, please correct me.

Question, how do I get the nipple off when I go to change
the water valve? *The old nut is all stripped out and drips
and can't be tightened any more without ripping something.

There is tool for everything, there must be a tool for this?
Or, should I breakdown and just call a plumber?

Many thanks,

It's called a ferrule and you need a ferrule puller.

Or very gently squeeze it with long nose pliers to make round again &
slide it off.

Or very, very carefully cut it with a hacksaw (or a Dremel) at a 45
deg angle (don't score the tube) and break it off.

When you install the new valve (use a 1/4 turn valve) use some pipe
dope (I know, they;re supposed to me metal on metal but teflon paste
helps)
Don't over tighten.

cheers
Bob
